Correct Answer: B

Rationale: Flat affect and social withdrawal are characteristic of negative symptoms in schizophrenia. Negative symptoms involve disruptions to normal emotions and behaviors, such as reduced emotional expression (flat affect) and social withdrawal. These symptoms reflect a decrease or absence of normal functions. Positive symptoms, on the other hand, involve the presence of abnormal behaviors or experiences, such as hallucinations and delusions, which are added to a person's experiences. Cognitive symptoms relate to difficulties with thinking, memory, and processing information, impacting cognition. Mood symptoms involve disturbances in mood regulation, which is distinct from the flat affect seen in negative symptoms.

Correct Answer: B

Rationale: Sertraline is a selective serotonin reuptake inhibitor (SSRI) commonly used to treat social anxiety disorder. SSRIs are a first-line pharmacological treatment for social anxiety disorder due to their effectiveness in reducing anxiety symptoms by increasing serotonin levels in the brain, which helps regulate mood and emotions. Methylphenidate is a stimulant primarily used in attention deficit hyperactivity disorder (ADHD) but not in social anxiety disorder. Lithium is typically used in bipolar disorder, while haloperidol is an antipsychotic medication more commonly used in conditions like schizophrenia. Therefore, the correct choice for treating social anxiety disorder is Sertraline (B).

Correct Answer: A

Rationale: Cognitive processing therapy is a specialized form of cognitive-behavioral therapy that has been shown to be highly effective in treating posttraumatic stress disorder (PTSD). This therapy focuses on helping individuals process and make sense of their traumatic experiences, leading to symptom reduction and improved coping mechanisms. Psychoanalysis, medication management, and group therapy can be beneficial in some cases, but cognitive processing therapy is specifically tailored for addressing the symptoms and underlying causes of PTSD. Psychoanalysis may not be as effective for PTSD due to its focus on unconscious conflicts rather than trauma processing. Medication management can be useful as an adjunct to therapy but does not address the core issues of PTSD. Group therapy can provide support but may not offer the individualized approach that cognitive processing therapy provides.

Correct Answer: A

Rationale: Patients prescribed bupropion should be educated to avoid consuming alcohol while on this medication to reduce the risk of seizures. Bupropion lowers the seizure threshold, and alcohol can further increase this risk. It is important for patients to understand the potential consequences of combining bupropion with alcohol to ensure their safety and treatment effectiveness. Choices B, C, and D are incorrect. Taking bupropion in the morning does not prevent insomnia; it is not associated with significant weight gain; and it is not a first-line treatment for anxiety.

Correct Answer: B

Rationale: The correct answer is B: Insomnia. Escitalopram, a selective serotonin reuptake inhibitor (SSRI), commonly causes insomnia as a side effect. Patients should be informed about the possibility of experiencing difficulty falling or staying asleep when starting this medication. Choices A, C, and D are incorrect because weight gain, diarrhea, and hypertension are not typically associated with escitalopram use.
